Scaling factors of exponentially scaled ticks not visible [possible solution included]

[kromuchi]

Using Matlab 2013b.

Scaling factors of exponentially scaled ticks are not printed in the current version.

figure;plot([1 2],[0.00001 0.00002]); 
plot2svg;

This is caused by a NaN-result of the call str2double(numlabels). However, a small fix in the function exponent2svg can solve the issue: Replacing

if ~isempty(numlabels)
    numlabels = str2double(numlabels);  
end

with

if ~isempty(numlabels)
    numlabels_tmp = str2double(numlabels);
    if(isnan(numlabels_tmp)) || size(numlabels,1) ~= size(numlabels_tmp,1)
        numlabels = str2num(numlabels);
    else
        numlabels = numlabels_tmp;
    end
end

tree times (for XTickLabel, YTickLabel and ZTickLabel) produces a correct figure. Maybe numlabels = str2double(numlabels); can simply be replaced by numlabels = str2num(numlabels); but I don't know the benefits of str2double and before breaking other things (e.g. in newer Matlab versions), the solution provided above should be safe.

A second bug in the same function exponent2svg causes scaling factors of ticks including a zero not to be plotted:

figure;plot([1 2],[-0.00001 0.00001]); 
plot2svg;

Solve this bug for example by replacing

if (length(indexnz) == length(numlabels) && max(indexnz) <= length(numlabels))
    ratio = numlabels(indexnz)./labelpos(indexnz);
else
    ratio = 1;
end 

with

if (max(indexnz) <= length(numlabels))
    ratio = numlabels(labelpos~=0)./labelpos(labelpos~=0);
else
    ratio = 1;
end

just wanted to let you know about the first release of fig2svg which should fix this issue:

https://github.com/kupiqu/fig2svg

please give it a try and if the issue is still there please report
